Triple Offset Butterfly Valve Sealing

HPX Superior Seal Design

The laminated seat is on the valve body placing it out of the direct flow path of the media. This reduces wear and the possibility of delamination and susceptibility to erosion. The solid disc seal is field replaceable without special tools.

Typical Competitor Design

The laminated seat is on the disc placing it directly in the fastest moving part of the flow path of the media. This increases wear and the possibility of delamination and susceptibility to erosion. The solid seal is integral to the valve body and is not field replaceable - it will require machining.
